Hi everbody, here is a little question regarding DNAT. Maybe you can help me out:
recently i upgrade to 2.4.17 on my x486 and installed the irc patch for iptables. Up to now i was just masquerading from my internal network eth0 to my external ppp0 and allowed external connections to the x486 on port 80,20,21 and 22 (suisse army knife: fw and websever plus ftp on one machine, please don't laugh...). Then i tried to test to forward the ssh to my notebook behind the x486 fw which work fine with iptables -t nat -A PREROUTING -ippp0 -p tcp --dport 22 -j DNAT --to 192.168.1.1 (my notebook on the internal network ...) But when I tried to Flush the Prerouting entrie i found two problems: 1.) The entrie stayed active even after i did a whole flush of iptables with iptables -F 2.) I couldn't see the current settings of PREROUTING When i enter iptables -L -vn i dont see my configured PREROUTING. Is this because I have an old version of iptables? My current iptable front end is version 1.2.1a but i am using a quit new kernel plus the newest patch... Thanks guys
